Hi,
When using the priority percent and bandwidth percent commands in a QoS policy-map, the priority percent option reserves a certain percentage of an interface's bandwidth, but also limits it to that bandwidth. Any of that priority traffic that exceeds its reserved bandwidth may be dropped. On the other hand, non-priority traffic that has bandwidth reserved with the bandwidth percent command is allowed to exceed that reserved bandwidth limit.
Why is that? Isn't it likely that your priority traffic might be your most important, or at least the kind of traffic that isn't tolerant of drops, such as real-time voice or video? Why would Cisco put that limitation on the priority percent command?
Thanks.
